I have inspection hatches on the sides of my diesel tanks. Currently they
have a rubber (might not actually be rubber) gasket sealing them, but one is
seeping slightly. I'm pretty sure if I tighten the bolts any more they will
shear. I think I need a stikaflex type sealant, but I can't find suitable
for use with diesel fuel... any suggestions, available in the UK preferably


SikaFlex 291 is approved for diesel, 292 is NOT.
